Vacuumless cosmic strings in Brans-Dicke theory
arXiv:gr-qc/9912053 · doi:10.1142/S0218271801000986
Abstract
The gravitational fields of vacuumless global and gauge strings have been studied in Brans-Dicke theory under the weak field assumption of the field equations. It has been shown that both global and gauge string can have repulsive as well as attractive gravitational effect in Brans-Dicke theory which is not so in General Relativity.
